获得功能价值

Question

我希望将数组函数的声明值 id_log 声明为 var id_L ，该怎么做？

function editcashiersession(id_log,d,e){
  var vdt = $('h_dttm').value;
  var vdt2 = $('h_dttm2').value;
  var tbd = _gel('tblcashiersession');
  var tr = d.parentNode.parentNode;
  **var id_L = ('id_log');**
  var curcashiersessioneditorid = _gel('rowcashiersession');

  if (lastcashiersessioneditorid) {

     _destroy(lastcashiersessioneditorid);

       if (lastcashiersessioneditorid == curcashiersessioneditorid) {

            lastcashiersessioneditorid = null;
            d.value = 'Edit Log';
            _gel('sessi_errmsg').innerHTML = '';
            return;
       }
}

Answer 1

var id_L = id_log;

这就是你想要的而不是

var id_L = ('id_log');

仔细检查你的javascript，因为你没有关闭if语句：

function editcashiersession(id_log,d,e){
  var vdt = $('h_dttm').value;
  var vdt2 = $('h_dttm2').value;
  var tbd = _gel('tblcashiersession');
  var tr = d.parentNode.parentNode;
  var id_L = id_log;
  console.log(id_L); //delete this line after testing.
  var curcashiersessioneditorid = _gel('rowcashiersession');

  if (lastcashiersessioneditorid) { //You forget to close this if

    _destroy(lastcashiersessioneditorid);

    if (lastcashiersessioneditorid == curcashiersessioneditorid) {
        lastcashiersessioneditorid = null;
        d.value = 'Edit Log';
        _gel('sessi_errmsg').innerHTML = '';
        return;
    }
  } // I added this in order to close it
}

此外，您的代码上未设置lastcashiersessioneditorid。
